Need help understanding my boat 2 batteries - solar and wind powered electrical system

I'm new here and checking if someone could enlighten me with an electric system I received with an old sailboat.
There are 2 batteries connected together, one for starting outboards and a 200AMP deep cycle one for the house, a solar panel and a wind turbine (not functioning until I'll give it maintenance and replace blades).
Problem is for now that it seems even on a sunny day the solar panel won't charge the house battery.
I haven't been able to try it while running the 2 outboards.
Is it possible that the solar only charges the starting battery, and the wind turbine (I couldn't test) works for the house battery? Or am I missing some settings to allow charging from solar?
I know that the installation has been done few years ago by a professional (that didn't label much things that I can understand) and seems to be all in good condition from my low expertise level.
The solar panel is at least 10 years old but I have limited information as for everything.. It does look in good condition though (unlike the wind turbine).
On the DC METER, I can read around 14.5-14.4V for both start and house battery when sunny without anything turned on, also a discharge of 1.3-1.7A in those conditions, and a charge of 0 no matter what I do playing with the different buttons/settings available.
On the second picture, the left Amp indicator is "ticking" hard when the sun hits and I have nothing on, but still no power goes to my house battery.
I believe the second one showing -+30 amps could be wind turbine related?
Also the starting battery shows a green dot saying it should be fully charged. The DC meter only gives me the house battery current capacity. It does stay constant over days of everything turned off.
The last pictured item is in stand by no matter what, so I guessed this one could be going with the outboards running?
If I turn on the water pump/lights or fridge I read a reduced voltage on the DC Meter for both starting and house battery (believe they are connected together, and heard from old owner that start battery should "overflow" when full to charge the house battery...)
I'm really keen on learning how all these systems work and will be very thanksfull to anyone taking the time to read me and give some advice!
